The month of Karkidakam is also a religious month for the Hindus who begin the first day of the month with a visit to Lord Rama or Vishnu temples.

On all the days of the month, the epic Ramayana is read in Hindu households, by Hindu organisations and in temples dedicated to Lord Vishnu. The Ramayana masam begins on July 17 and ends on August 16. The reading of the Ramayana begins on the first day of the month and ends on the last day. The famous Malayalam version of the Ramayana titled Adhyatma Ramayanam Kilippattu written by Thunchath Ezhuthachan is the one recited during the month. After lighting the evening lamp, people sit before the ‘Nilavilakku’ (traditional Kerala lamp) and recite the Adhyatma Ramayanam.
